#### Polar / Cartesian Toggle

This icon switches your coordinate system between Polar and Cartesian modes. This changes the coordinate system PC-DMIS uses to display the point or center values for the auto feature.

In Polar mode, when the icon is raised, the values are displayed as radius, angle and height (shown as R, A, and H in the dialog box). The height depends on the workplane currently being used. If the current workplane is ZPLUS, the height is the Z value. In this mode, if you are modifying a Vector Point feature, and you update the value of the angle in the A box, PC-DMIS automatically updates the corresponding surface vector of the feature. This helps you to update the surface vector in measurement routines that don't use CAD. For more information on the surface vector value, see "IJKT Surface boxes".

Inner/Outer/None toggle

In Polar mode, if you select the Azimuth angle (A) or you select the In or Out option from the drop down list and the proper symmetry is set (Cylindrical or Spherical), the surface vector is correctly defined. If you select None, no change is applied to the surface vector.

The Inner/Outer/None is only available when the Polar mode toggle option is selected and is applied either when you:

- Select the Azimuth (A) data value, and validate the data.

- Change the option from In to Out (or Out to In). It is not applied when you click on your CAD model in the Graphic Display window. If the CAD is clicked on in the Graphic Display window, you get the surface vector of the exposed CAD.

The Inner/Outer/None information for auto vector and auto surface points are not explicitly exposed in the Edit window when in Summary, Command or DMIS modes.

In Cartesian mode, when the icon is depressed, the values are displayed in XYZ.
